Weirdest Problem Ever on a dv6000t....

My dv6000t ( T7200 Core 2 Duo) turned itself on and it was running on battery.
The OS didn't load but the all the lights on the keyboard was on and the fan started to spin continously.

This happened like twice...

Paranormal activity or serious power flaws ???

I took the battery out to stop this weird ****.

Anybody facing the same problem.

Grrr

 

Were you able to boot to OS with the cable plugged in?
Can you access BIOS (press F10 after you turn it on)?

 

The screen didn't turn on......and it was not plugged in....
It was just lying on my desk with the power cord unplugged before it turned itself on...

It was neither on sleep, hibernate or anything like that....I did a plain old shut down an hour before this thing happened...i tried to recreate the problem but it happens randomly...i though the fan would explode it was running at such high speeds....

 

Call a priest, because I'm stumped.

 

Can anybody help me out with this problem...

 

Well said Or just call hp noobz

 

Don't worry about the fan. Is it possible that the lid touches the on/off button? I can't think of any other explanation

 

Hi vassil...

that was my initial doubt too..but the OS doesn't load so that means its not the on/off button......the lights, the fan turn on and i suspect the high pitched sound is from the Core 2 Duo...

wats happening?...

 

A motherboard problem, I assume. Sporadically touches off a few contacts and lights come on. Return it to HP for repair / replacement.

 

im having wierd problems with my dv6000z as well if i want to turn it on and press the power button sometimes the lights or leds w/e u call them just turn n off nothing happens i have to press the power button a few times before it actually starts up i checked the battery n the battery is fully charged
im probally gona send this back n get my money back

 

I talked to a HP Tech rep through live online chat...unfortunately i didnt have my notebook with me ..i explained him the problem and he told me to do a battry diagnostic test at this link

Anyway I will keep you posted as the story unfolds...

If you google you will find people having the same problem with some of the Dells and HP pocket PC...in the Dell case...a BIOS update took care of things..

Its a sweet laptop ...this is the only issue...

 

Bios update may fix it.... but HP needs to have people report the problem in mass so they fix it.

On the consumer models (vs the business line) remember that these models:

1: Get all the gee-wiz gadgets (compared to the business line)

and

2: The product cycles are VERY short, most models only running a few months, instead of a year + of the business models so they're going to be more "buggy" than a business model.

3: In some cases a fix may never be done, since the product cycles are so short. Models that are slated for a long production run getting more "attention" both during the design /testing phase and after the unit goes into production... Since it will be in production longer, have to be supported longer. Another issue on the business line is the mfg is going to throw more man-power into a problem, because the machine is being used for "business".

 

I'm having the same problem, I own a dv6040us and it turned on by it self a couple times. When it happened, there was aloud high pitch noise that was continous and another that beeps on and off. The fan turns on at the highest speed but the screen does not turn on. I called HP but they told me they had no idea what I was talking about and suggested I send it in to get it checked. I'm currently in school and have an online class so it's hard for me to send it and wait for weeks to get it back. If someone has any Idea how to fix this at home please help!!!!!!!!

 

Hi jbravo83...

I am so glad to know that I am not the only person facing this weird problem.
I am facing the exact same problem like you described.

Well, I am going to run some BIOS updates ( Latest BIOS version for this laptop was released on 9-20) and battery health scan to see if it can fix the problem.

I am sure there are many more out there probably the unit is getting turned on during night times or when they are not around...People out there keep a close watch on this baby !

 

the dv6000t BIOS version is F.02 but for the AMD version 6000z is F.18.

Anyway, the HP rep told me that this problem occurs when there is static in the notebook and asked me to follow these steps to drain the static.

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power

Anybody buy this explanation ??

I followed the steps and the problem didnt repeat so far...

 

Static electricity is tricky. I hope this helps

 

After doing some searching ..i came to the conclusion that static is probably the issue...

I dont know if that is like a permanent fix or not...but i am gonna keep my eyes open ...

Some of the users on the website also had similar problems and the solution was either a BIOS fix or to drain the capacitors by following the steps above..

Anyway...so far no problems...

Thanks for all the inputs everybody

 

Just a shot in the dark: Could your system have a problem with Stand By? I am thinking this because you say the screen doesn't turn on and the OS doesn't load when it spontaneously "starts".

First option: leave the lid up and see if the condition ever happens. This might indicate the lid, when closed, is somehow touching the power button.

Second option: Go to Control Panel - Power Options; make sure the Power scheme is set to Portable/Laptop and then set ALL of the Setting for Laptop scheme to "Never". You might also want to verify that Hibernate is NOT enabled.

These may or may not cure your problem, but they will eliminate them as possible causes, and provide you with more information if you have to send the unit back to HP for repair. Good luck. Keep us posted.

 

HI

My 6040ca just woke me up with the same problem. Scared the hell out of me. The laptop was last used @ 2pm and has been sitting on my coffee table unplugged and hibernated.

Anyhow I'm try the static charge solution above and see if it happens again.

BTW, anyone notice that battery will drain even though the unit it turned off?

Pat

 

It may lose 1-2% but not more. Of course it depends on how long you leave it but anything more than 5% is weird.

 

Hi Folks,

From my intense googling and research; the reasons for such behavior is usually attributed to...

1. Outdated BIOS
2. Power Management in Windows ( Set it to Never for everything …seems to work for some folks whose comps shutdown or startup on their own but note they do boot into OS eventually)
3. BIOS settings on some computers with the setting “ WAKE UP ON LAN”.
And last but not the least…
4. Static electricity in the capacitors

AMD based DV6000 laptops have updated BIOS, download it from HP and see if the BIOS can fix the problem even though the BIOS fix may not be for the same problem it might just fix it anyway.

The problem with static usually happens on newer laptops ( don’t ask me why!!) and after I did the steps as suggested from the HP rep the problem never occurred again.

Other Dell, Toshiba folks also reported the same problem on some newsgroups. In fact one dv9000t owner in these forums had a similar problem.

Pat download the HP battery Utility to diagnose your battery.


But one thing still amazes me how much static are in these capacitors that they can turn a fan at full speed and make that high pitched noise and glow all the LED’s.

Something to ponder on….


Well I didn’t go to school for electrical engineering or chip engineering may be some pros here can shed some light on this behavior.

Hope this helps.

 

Take a look here, page 94 - Table 4.1. These are some pretty solid voltages

 

Well I downlaoded the latest bios and ran the HP battery check. I'll post back if the problem ever comes back.

Thanks guys!!

 

This has now happened to me more than once.
Today, I put the notebook in the carrying case, and put it in a closet.
4 hours later when I went to retrieve it, the carrying case was hot as h*ll. I tok the notebook out, and it was even hotter. I mean you could cook on the thing.
After letting it cool down, I found that the battery was completely drained - obviously it had turned itself on.

The previous time, I was taking it with me on a trip, and when I went through airport security and took the notebook out of the case, I found it had turned itself on.

I think this is a design problem. The fancy/stupid touch-sensitive buttons for QuickPlay are involved I think. (The time at the airport, it had gone into Quickplay by itself.)

BTW - my notebook was custom ordered/shipped in December, and out of the box defective (I will be returning it): closing the lid will not activate any power features - the LCD stays on/backlit, and none of the Windows power options for what to do when the lid is closed work.

This is my 3rd bad HP notebook in a row (2 DV5000's and now the DV6000).

 

I have a hp 8000 and it works fine.

a few weeks ago I had the dv6174cl ( i took it back), featuring the core 2 5500. I never had this problem. I did have multiple other problems though, including what I thought was poor quality build, a dvd drive that buzzed and rattled anything I set the notebook on, flimsy body (it was worped and the front right side never rested on a flat surface with the rest of the notebook), and, the worst, was a buzzing noise that it emitted CONSTANTLY. HP told me it was a hardware prob and I was to send it back. I got it at Costco though and returned it. I got another one and it had the same exact problems. Returned it too.

Another friend of mine though had another dv6000 series notebook that he got at Costco featuring a turion X2. He had your problem. It seemed to work fine for a week or so, then it would turn itself on, lighting up but not booting into the os. he was unable to turn it off and also had to remove the battery. He was not able to find a fix and returned it also like I have.

I think that the new HP laptops are beautiful. They are sleek, light, and are of great ergonomic design(for the most part). But they suffer from what I think is poor quality. My 8000 series is great, I purposely went with the older series because they built them like bricks. o'well. I hope you get this fixed without having to bring it back.

I'm now on my 4th hp laptop....1 14'' 2000 series with a bad pixel, 2 15.4 6174's with multiple problems, and now my dv8408us

 

Guys, the problem is with the LCD dim switch. I am a laptop tech and own a DV6253CL. At work we see the DV6000 come in for this problem sometimes, although we dont see many DV6000's in general.

Anway, it powered on because the LCD dim switch momentarily became unclosed (an open circuit) and then closed again. This causes the computer to power on, but as soon as the power management IC on the motherboard realizes that the lid is closed again it one of a number of things based on the manufacture. In this case, it stays powered on but doesn't load to windows.


nucleus1872, that insn't "static". that is merely the charge built up in the capacitors as they are designed to do. you will notice that if you unplug your desktop and then press the power button that the computer will turn on for a quick second. When you press the power button it will power on the computer because there is stil enough charge in the capacitors to make the motherboard think that the system can power on.. as soon as the caps are drained it turns off. Without these capacitors, computers would cease to function.

 

So what can be done to remedy this situation?

I'm planning on purchasing a dv6253cL when the Costco $100 off coupon comes into effect and would like to cover my bases just in case something goes wrong with it.

 

What is an LCD dim switch?

 

My DV 6000 series does the same thing as described in this forum. It was purchased about 6 months ago, but I just started installing software, updates, etc. This is most distressing and seems a safety issue as well. HP seems ignorant about the problem. They want me to restore the original configuration before sending it in for service. Of course, all my work will be lost. Will HP fix the problem. Unfortunately, it is too late to return back to the supplier for a refund. Also, the battery seems to drain rapidly when the notebook is powered down.... about 10% per day.

nice explanation... after doing some google research, Phoenix BIOS 1-2-2 beep came down to Video Card memory error.

i just sent my notebook to HP and hopefully they fix the problem... i got my xbox elite so i have to burn time playing my console while waiting for my notebook!
